In apparatus controlling an exhaust-driven turbine-driven compressor super-charger for an I.C. engine by means of a by-pass valve 16, Fig. 1, which is connected to two diaphragms 17, 18, Fig. 2, in a control device chamber 6 defining first, second, and intermediate chambers 30, 31, 32, the outer face of diaphragm 17 is larger than the outer face of diaphragm 18, chambers 30, 32 are constantly subjected to the compressor inlet pressure and chamber 31 is subjected to compressor outlet pressure. The pressure in the compressor air inlet conduit 4 communicates with chamber 30 through conduit 7 and the compressor discharge pressure communicates with chamber 31 through conduit 8. A bleed orifice 24 equalizes the pressure in chambers 30, 32. The pressure differential on diaphragm 18 moves valve 16 against the action of springs 21, 22, and if diaphragm 18 fails diaphragm 17 continues to control valve 16. Compressed mixture which escapes past rod 25 passes through groove 25, passage 28 and thence through bore 27 to the upper side of diaphragm 17.

Headings H3T, H4D and H4J. Portable apparatus for aiding blind purposes comprises a transducer 16, Fig. 1, transmitting ultrasonic acoustic waves on a cyclically varied frequency and receiving means 17 feeding a frequencychanger 19 also fed with a local signal, on a frequency varying cyclically in conformity with that transmitted, to produce an audible beat frequency signal, and sound reproducing means 24, the frequency sweep transmitted covering a frequency range a plurality of times greater than the frequency range of the beat frequency signal. In the embodiment, the frequency modulation is of sawtooth form, there are two spaced receivers, each receiving channel 11 incorporates a low-pass filter 21 and a range equalizer 22, the frequency sweep of the transmitted wave is from 40 kc/s. to 60 kc/s., and transducers 16, 17, preamplifiers 18 and bone-conduction reproducers 26 are mounted on a spectacle-like frame, Fig. 4. Thus target range is estimated from the average of the beat frequencies heard and target direction is judged from the frequency difference and the mean frequency, or the user turns the head to nullify the frequency difference. Use may be made of the break in the signal heard, corresponding to the relatively short time when the beat frequency rises beyond audibility. Transistor circuits. Figs. 6, 10.-The frequency-swept oscillator 12, Fig. 1, comprises a transistor multivibrator, Fig. 6, wherein a sawtooth wave is impressed on the junction of resistors R1, R2.

Abstract: 1,248,571. Animal feed-stuffs. J. WHITE. 5 Dec., 1968 [6 Sept., 1967], No. 40636/67. Heading A2B. A process for the production of animal feed-stuffs from vegetable matter comprises applying pressure to the vegetable matter to separate a liquid portion therefrom thus leaving a residue enriched in protein content compared to the original vegetable matter, and using the liquid portion as a substrate for the growth of micro-organisms so that the liquid portion obtains a solids content rich in protein. The solids from the liquid portion and the protein-enriched residue may be used separately or in admixture as an animal feed-stuff. Suitable vegetable matter is grasses (including rice), leaves, foliage, hay, straw or carrots, preferably comprise corn. Yeast may be added to the liquid portion to cause the growth of micro-organisms. The liquid portion may be heat treated to pasteurise the liquid and to coagulate the protein present in the liquid portion.
